To all whom it may concern.'

Be it known that I, ROBERT B. GRIMM, a citizen of the United States,residing at Pittsburgh, in the county of Allegheny and rState ofPennsylvania, have invented certain new and useful Improvements inIVat-er- Closet Valves, of which the following is a specification. f

y invention consists of an improvement in water closet valves. l 4

It has for its object to provide a valve v controlling the flow ofvwaterto the tank,

subject to the float, which shall be noiseless in its action, simple inconstruction, of few parts, durable andv effective. Y

It consists of a valve mounted upon a vertical hollow inlet stem, and isconstructed and adapted to operate in the manner hereinafter described.l

In the drawings: Figure 1 is a sectional view of a portion of a tankprovided with my improved valve. Fig. 2 is a vertical sectional view onan enlarged scale, showing the valve open and its connected parts. Fig.3 is a partial similar sectional View, showing the valve closed. Fig. 4is a cross section on the line IVQFV. of Fig. 3. Fig. 5 is a Viewsimilar to Fig. 3, showing a modified construction. F' 6 isa crosssection on the line VI. VI. o Fig. 5. Figs. 7 and 8 are detail viewsshowing a modified arrangement of the lever connection for the valve.Fig. 9 is a sectional view showing t-he manner of connecting a porcelainterminal tube.

'Ihe valve A is for the purpose of controlling the fiow of water intothe tank 2 of a water closet under the control of a float of usualconstruction, as the water is flushed from the tank by the customaryoutlet valve 3 indicated in dotted lines. Water is supplied to the valveA by pipe 5 and any suitable fitting or connecting devices adapted formounting on the tank bottom and adapted to deliver the water through aterminal pipe or tube 6. Said tube, which may be of brass or othersuitable material, is ixedly secured in the top of a hollow fitting orbase section 7 adapted to be secured to the tank by a nut 8. 'Ihe waterconnected directly to said section 7, but in the case of non-standardthreads, I may use a bushing 9 and union 10, with the necessary packingwashers, etc., to make a tight joint, for connecting. the pipe 5, asshown.

Slidingly mounted on the vertical hollow stem or tube 6 is a bushing 11to which is supply pipe 5 may be connected by threads the cap 12containing a rubber packingwasher 13 a sealing seat on top otube 6. Thetop of bushing 11 is hollowed out, as shownv at 14, and a pluralityofcirculat-ion ports 15 eX tend vertically through it for escape vof asin Fig. 2.

The valve is raised and lowered by the action of float 16 mounted on theend of rod 17 whichV is adjustably mounted to the end of the arm 18.Said arm is fulcrumed at 22 on a pivot, pin or rivet at` the upper endoflinks 20. Said links are pivotedat 21 to the top of fitting 7 and attheir upper ends are deflected toward the center of the valve so as tobring the pivotal joint 22 close to the pivotal connection 23 of arm 18with capy 12. By this means the leverage of float 16 is increased to amaximum.

.If desired, the circulation ports 15, instead ofbeing through thebodyof the bush ing 1l, may be between its exterior andthe inner side ofcap 12, as shown at 15. In such construction the bushing 11 may begrooved across the top, as indicated at 1 4. The stem 6 is secured inany suitable manner in the top of section 7 or may be made integral withit if desired. In Fig. 9 I show a porcelain tube 6a mounted by its base6a -and secured by a retaining nut 6c in the top of fitting 7a. Bymaking the tube of porcelain or other similar material, I avoid any wearor abrasion due to the action of the valve, flow of water, etc., thuskeeping it at its highest efficiency. If desired the -connections 20 maybe in one piece, cenftrally arranged, as in F ig. 7, extending upthrough a central slot in arm 18a .and pivoted thereto by pin 22'1 beingconnected to the cap 12 in the same manner already described.

Connection 20, above the pivotal joint, is provided with flanges 20bwhich rest across the top of lever 18a so that if the pivot pin is lostor broken, the lever action will continue unimpaired, due 'to the flangeengagement. Connection is made with the base by a pipe 24, the inner endof which communicates with an upwardly directed port 25 in the base 7and which is in the line of How of the water downwardly through port 15.The other end of pipe 24 communicates with a pipe 26 leading through thebase of the flushing valve seat to the closet bowl. By this connection Iprovide adapted to make water downwardly when the valve is raised,

.no f

'Y after each l for the' necessary flow of water to insure a sealing bodof water in the bowl outlet u'shing operation.

What I claim is 1. A water closet valve comprising a hol- 4 lowcylindrical supply stem and a cylindritank, of a cylindrical verticallymovable -valve embodying a t-ermlnal cap having a central cylindricalbore slidably mounted on said stem and having a sealing gasket in thecap and circulation ports within the body portion of the valve spacedoutwardly beyond the central bo-re, and a pivotally mounted leverconnected with said valve and having a float, substantially as setforth.

3. The combination of a circulation fixture adapted for connection witha tank and a water supply, a hollow cylindrical stem extending upwardlytherefrom, a pivotal support mounted on the fixture, a cylindrical valvehaving a central cylindrical bore slidably mounted on said stem andhaving a covering cap, a sealing gasket inserted in the cap,anddownwardly extending circulation ports within the body portion ofthevalve spaced outwardly beyond the central bore, and an operating leverpivotally connected with said valve and pivotal support, substantiallyas set forth.

4. In a valve, the combination of a vertically arranged hollowcylindrical stem open at its ends, a base therefor having a passage wayadapted for connection with a source of supply and in communication withsaid stein, a supporting link pivoted to said base, a cylindrical valvehaving a central cylindrical bore slidably mounted on said stem andhaving an upper portion containing an inserted sealing gasket anddownwardly directed circulation ports within its body spaced outwardlybeyond the central bore, and an operating lever pivotally connected withsaid valve and with the upper end of said supporting link, substantiallyas set forth.

5. In a valve, the combination of a vertically arranged hollowcylindrical stem open at its ends, a base therefor having a passage wayadapted for connect-ion with a source of supply and in communicationwith said stem, a supporting link pivoted to said base and having anupper deflected pivoting terminal, a cylindrical valve having a centralcylindrical bore slidably mounted on said stem and having an upperportion containing'an inserted sealing gasket and downwardly directedcirculation ports within its body Aspaced outwardly beyond the centralboreyand an operating lever pivotally connected with said valve and thedeflected ivoting terminal of said supporting link, substantially as setforth.

In testimony whereof I hereunto aix my signature in the presence of twowitnesses. ROBERT B. GRIMM. lVitnesses: 1
